I recall that the context for this suit is that this LL member is a music teacher (?piano) and he uses this suit when he teaches. The design is based on an old vintage coat and vest but I can't seem to find the thread where the details are discussed. The suit looks vintage because it is supposed to be. As a uniform/costume for his profession, I think it is not an unreasonable choice.
